Is there an aggregator of IT conferences or video / reports from them in nature?

Question

Computer networks

There are many conferences, of course, many have a website / twitter, but it's still difficult to keep track of everyone, and most importantly, do not forget to check the sites / bookmarks afterward.
Is there something similar to the conference aggregator in nature? Or how do you solve this problem?

Answer 2

I don’t know the global aggregator, but according to the Microsoft technology stack there is https://www.techdays.ru/

Answer 3

It seems that something similar (at least a video aggregator) was done, but judging by the dates, the project is slightly dead.
